SUPPORT FOR RUBBER-TIRED WHEELS.

SPECIFICATION forming part of Letters Patent No. 719,615, dated February3, 1903.

Application filed May 15, 1902- SerialNo.107,383. (No model.)

To all whom it may concern:

Be it known that I, WILHELM ScHULzE, re siding in Gera, Germany, haveinvented certain new and useful Improvements in Supports forRubber-Tired Wheels of Carriages,

of which the following is a specification.

The present invention relates to a device for supporting vehiclesprovided with rubbertired wheels, the object being to provide such to adevice which will prevent a flattening out of the tire by the pressurewhile the carriage is stored for a long period of time, the wheels beingsupported on blocks of angular crosssection, extending along the tirefor a consid- I 5 erable distance outside the tires and under the rims,so that the tire is relieved of pressure and flattening prevented.

With this object in view the invention consists in the improvedconstruction, arrangement, and combination of parts hereinafter fullydescribed and afterward specifically claimed.

In the accompanying drawings, Figure 1 illustrates part of acarriage-wheel supported by the new device. Fig. 2 is a plan Viewshowing the rim and the spokes of the wheel in section. Fig. 3 is avertical section. Fig. 4; shows the device, partly in plan and partly insection, on an enlarged scale.

a a are wooden blocks of angular crosssection' and of a curvatureapproximately that of the periphery of the rubber tire.

The two blocks are rabbeted or cut away at their inner upper edges andare connected 5 bya metal blade 6, pivoted to the block a, as

clearly shown in Fig.4, and extending through an opening in the block a,said blade having teeth on one edge, which engage a slotted plate d,secured on the lateral face of block 0 a. A flat spring may be used topress the notches or teeth into engagement with the -xplate d at the endof the slot through which the plate I) is passed.

c and c are springs loosely mounted at their ends in suitable sockets ofmetal or other convenient material inserted in the wood of the blocks aand a in perfect alinement, so that the springs have a tendency to pressthe blocks a a. apart when the blade 6 is shifted out of engagement withplate 01. A pin 6 at the end of the blade I) prevents the blocks a afrom being entirely separated. When the springs are allowed to expand totheir fullest extent, the block a strikes against said pin 6, the endsof the springs being still in place in their sockets. If a wheel is tobe placed between the blocks, the springs are compressed .by hand tillthey approach close to the sides of the rubber tire, a closer approachbeing prevented by the thickness of the rubber tire. In pushing theblocks together in the described manner the springs c a will becompressed, and the blade I) under the influence of the flat spring willbring its teeth successively into engagement with the metal plate on theside surface of block a, and thus lock the blocks in their finalposition, in which the rim of the wheel resting on top of the blockswill support the Wheel and relieve the rubber tire from all pressure.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is-

A support for rubber-tired Wheels comprising two curved blocks one ofwhich is pro vided with a transverse slot and a plate on its outer faceprojecting slightlyinto said slot, a toothed plate pivoted to the otherblock passing through the slot and normally springpressed intoengagement with said plate, a pin at the outer end of the blade toprevent the entire separation of the blocks, and springs mounted insockets in the inner faces of the blocks, normally pressing the blocksapart substantially as described.

In testimony whereof I affix mysignature.
